FAQ

Reliability Challenges: Harmonics are current pollutants generated by non-linear loads, such as Variable Frequency Drives (VFDs) and precision switching power supplies. They cause grid waveform distortion, leading to unexpected downtime of sensitive control equipment, abnormal motor heating, and shortened transformer lifespans.

Safety Risks: Under extreme operating conditions, harmonics may trigger system resonance, which can lead to severe physical damage to the capacitor banks within reactive power compensation units.

Phenomenon Description: A voltage sag refers to a sudden reduction in voltage lasting less than one second, typically caused by short-circuit faults in remote parts of the grid or the startup of large-scale loads.

Economic Impact: Despite their brief duration, voltage sags are sufficient to trip high-speed production line protections, resulting in complete system downtime. In industries such as semiconductor and pharmaceutical manufacturing, a sag lasting only a few hundred milliseconds can lead to hours of recovery time and costly material scrap.

Configuration Logic: The LSVG integrates the rapid, continuous regulation capabilities of SVG modules with the large-scale compensation advantages of traditional capacitor banks.

Value Proposition: While ensuring high-speed response and mitigation precision, the device utilizes reactive power capacitors to significantly lower the unit cost per kVAR. This provides an ideal balance for users seeking high-performance solutions with optimized cost-efficiency.

Design Intent: Over 90% of power disturbances in industrial environments are voltage sags rather than total outages. Unlike UPS systems that require frequent battery replacements, the Supercapacitor-based DVR (Dynamic Voltage Restorer) is specifically engineered for sag mitigation.

Operational Advantage: Supercapacitors feature a cycle life exceeding 500,000 times and a wide operating temperature range. With a long service life and low maintenance requirements, they contribute to a lower Total Cost of Ownership (TCO).

Technical Features: TCD switches utilize full power electronic control to achieve "zero-crossing switching" technology. This allows the capacitor banks to be activated within milliseconds without generating any voltage surges or inrush currents.

Application Scenarios: This performance is essential for environments with highly fluctuating loads, such as welding shops and elevator systems, ensuring real-time compensation while extending the operational life of the capacitors.
